Yep, PCV and Fuel Moto's the way to go. I thought about the PCIII for my 08 until I talked to Jamie. I went with the PCV and couldn't be happier with the bike's performance and their support.
they make them for as far back as 02 from what i understand. my box is here and it's got the label 08 harley touring retrofit, pn 15-818, and the week after i got mine, i found out that they're making them for the earlier models too. might wanna call jamie or keith at fuelmoto, they're great guys, and very interested in having a new customer, i was so impressed with the way they treated me with my pc-v, and i couldn't be happier.
I have the PCV with autotune on my 08 from FuelMoto. Works great. I aminly wanted it becasue it was smaller than the PCIII but being able to add the Autotune modules was a big plus for me.
does anybody know if i could use the pcv on a o7 electraglide or should i use the pc3 ?
I've had the PCV installed on my '07 SG since January, and added Auto-Tune a week later. Buy from Fuel Moto and you'll get an accurate map for your configuration plus excellent customer service. If you haven't purchased slip-ons and an AC, definitely consider their Power Package, which IMO is the best Stage 1 kit available--definitely the best if cost is factored in. Do a search here on "Fuel Moto" for more feedback from customers.
The PCV costs maybe $10-20 more than a PCIII but has more features, is smaller, and you can add AT later if you wish. Also, it can be used with a simple on-off switch to allow toggling between two maps on the fly--one for mileage, one for cooling. The PCIII can be used with switch but requires the optional ($150) Multifunction Hub to work.
